:: CIP Plant Nears Completion at Simmers' Buffelsfontein Mine

Gold-miner Simmer and Jack Mines (Simmers) reported on Monday that a new 170 000 t/m carbon-in-pulp (CIP) plant, at its Buffelsfontein gold mine (BGM), in the North West province, was nearing completion.

The plant has been constructed at a cost of R58-million and commissioning of the new circuit is scheduled to commence in October 2007, the company said.

By replacing the old filter plant and zinc precipitation circuit, Simmers expects that the upgrading and expansion of the metallurgical plant will reduce plant treatment cost per ton treated by 25% from R52 p/t to R39 p/t; increase plant throughput capacity by 21 % to 170 000 t/m; and increase gold recoveries by 3% from 93% to 96%

The plantís additional throughput capacity will be used to treat low-grade surface waste rock dumps. The CIP plant will allow BGM to economically process low grade dumps that were previously untreatable through the old filter plant due to the fineness of the ore in these dumps.
